Write a variable expression to describe the rule for the sequence. Then find the 100th term. 35, 36, 37,...

Dmitry [639]

Given expression is 35, 36, 37, 38...

First term a = 35

Common difference d = 36-35 = 1

Nth term of arithmetic sequence is:

$n_{th} = a+ (n-1)d$

$n_{th}= 35+(n-1)(1)$

$n_{th} = 34+n$

To find the 100th term, substitute n = 100

$n_{100} = 34 +100$

$n_{100} =134$

Correct option is B

Please help!!!!!!!!!!!

Let's take this problem step by step:

To find the ordered pair of the system:

⇒ must set both equations equal to each other

⇒ and solve for 'x'

Let's solve:

$x^2-2x+3=-2x+19\\x^2-2x+2x+3-19=0\\x^2-16=0\\(x+4)(x-4)=0$

Let's find the x-values:

$(x-4)=0\\x=4\\\\(x+4)=0\\x=-4$

Let's find f(x)'s value for each 'x':

$x=4\\f(4)=-2(4)+19=-8+19=11\\\\x=-4\\f(-4)=-2(-4)+19=8+19=27$

Answer: (4, 11), (-4,27)

Hope that helps!

An airline finds that if it prices a cross-country ticket at $300, it will sell 400 tickets per day. It estimates that each $10

lions [1.4K]

Answer:

price = $190

quantity = 950 tickets

Step-by-step explanation:

revenue = price * quantity

n = number of $10 price reductions

price = 300 - 10n

quantity = 400 + 50n

r = (300 - 10n)(400 + 50n)

recognize these as the factors of a quadratic that opens down

the vertex will therefor be the maximum revenue

the roots are:

300 - 10n = 0

300 = 10n

n = 30

400 + 50n = 0

50n = -400

n = -8

vertex is at mid point of the roots

n = (-8 + 30)/2

n = 11

price = 300 - 10n

price = 300 - 10(11)

price = 190

quantity = 400 + 50n

quantity = 400 + 50(11)

quantity = 950
